The blockbuster trade between the Boston Celtics and the Cleveland Cavaliers that was in danger of falling apart is back on, with the Celtics agreeing to give up a second draft pick as compensation for Isaiah Thomas' injured hip.

The two teams were facing a 10 a.m. Thursday deadline to complete the deal.

The Cavaliers were seeking extra compensation in the trade because they felt the Celtics undersold the significance of Thomas' hip injury and the amount of the coming season he would miss. In the original deal to send Kyrie Irving to Boston, the Cavs also agreed to take forward Jae Crowder, rookie center Ante Zizic, and the Brooklyn Nets' first-round draft pick in 2018.

Thomas injured his hip in March during the regular season and missed two games. He reinjured the hip during the Eastern Conference semifinals and then missed the final three games of the Eastern Conference finals against the Cavs.

After the trade, Celtics general manager Danny Ainge confirmed that the hip was still an issue for Thomas and that he would most likely miss the start of the season but said he "should be fine" at some point during the season. Thomas and the Celtics opted against surgery on the hip.

Thomas was emphatic during an interview with ESPN on Tuesday that he would be fine.

"I'm going to be back, and I'm going to be the same player again," Thomas told ESPN. "No doctor has told me anything different than that."
